Description
技术领域technical field
本发明涉及通信技术领域，特别的指一种随机接入方法、终端及基站。The present invention relates to the field of communication technologies, and in particular, to a random access method, a terminal and a base station.
背景技术Background technique
ITU(International Telecommunications Union国际电信同盟)定义了5G的三大类应用场景并提出了相比4G更具挑战性的关键指标能力，要求支持100Gbps+的峰值速率和更低空口时延(增强型移动带宽eMBB的空口时延为4ms,低时延高可靠通信URLLC的空口时延为0.5ms)。为了实现相比LTE(长期演进)块几倍的峰值速度，考虑到当前传统无线通信频谱(低于6GHz)资源严重不足的现状，5G将很可能会利用相比现有LTE使用的频谱高很多的频谱资源(例如毫米波频段在10GHz以上)进行无线通信。ITU (International Telecommunications Union) defines three major application scenarios for 5G and proposes more challenging key index capabilities than 4G, requiring support for 100Gbps+ peak rate and lower air interface delay (enhanced mobile bandwidth). The air interface delay of eMBB is 4ms, and the air interface delay of low-latency and high-reliability communication URLLC is 0.5ms). In order to achieve peak speeds that are several times higher than LTE (Long Term Evolution) blocks, considering the current serious shortage of traditional wireless communication spectrum (below 6GHz) resources, 5G will likely utilize much higher spectrum than the existing LTE uses. The spectrum resources (for example, the millimeter wave frequency band above 10GHz) can be used for wireless communication.
因为超高频段固有的信号衰减过快的特点，为了提高信号覆盖范围，未来使用超高频段的5G基站和终端在上行和下行传输上都很可能将采用波束赋形的技术。因为成本的限制，起码在部署初期，5G通信器件将采用模拟波束赋形技术。模拟波束赋形技术是指在同一时刻通信器件只能从/向有限方位内的另一通信器件接收/发送无线信号。因终端的天线个数和体积限制，不同厂商终端的天线阵列可形成的发送波束(朝向不同方位)的数目很有可能是相等的。Because of the inherently fast signal attenuation of ultra-high frequency bands, in order to improve signal coverage, 5G base stations and terminals using ultra-high frequency bands in the future are likely to use beamforming technology in both uplink and downlink transmission. Due to cost constraints, at least in the early stages of deployment, 5G communication devices will use analog beamforming technology. Analog beamforming technology means that a communication device can only receive/transmit wireless signals from/to another communication device within a limited azimuth at the same time. Due to the limitation of the number of antennas and the volume of the terminal, the number of transmit beams (oriented in different directions) that can be formed by the antenna arrays of the terminals of different manufacturers is likely to be equal.
在传统的LTE中，终端与基站之间需要经过四次信令交互才能完成基于竞争的随机接入过程。在第三条信令中，终端需要携带自己的唯一标识号，以便基站做出冲突解决决定并且在向终端(信号传输条件较好的终端)返回的第四条信令携带终端唯一ID以告知竞争终端们哪个终端赢得了竞争。In traditional LTE, the contention-based random access process needs to be completed through four signaling interactions between the terminal and the base station. In the third signaling, the terminal needs to carry its own unique identification number so that the base station can make a conflict resolution decision and the fourth signaling returned to the terminal (terminal with better signal transmission conditions) carries the unique ID of the terminal to inform Competing Terminals Which terminal wins the competition.
当前RAN1 3GPP已经同意了起码在免于竞争的随机接入中，在终端收到一个RAR(Random Access Response，随机接入响应)回复之前，可以发多次第一消息Msg.1。可以理解的是，如果终端有多个发送波束，这些Msg.1可以在终端不同的发送波束上进行发送。但因为波束具有方向性，所以发送波束的选取会影响基站侧接收Msg.1和接收后续信令和数据信号的能量。因此，在随机接入流程中如何选取终端的发送波束是需要解决的问题。The current RAN1 3GPP has agreed that at least in the contention-free random access, before the terminal receives an RAR (Random Access Response, random access response) reply, the first message Msg.1 can be sent multiple times. It can be understood that, if the terminal has multiple transmit beams, these Msg.1s can be transmitted on different transmit beams of the terminal. However, because the beam is directional, the selection of the transmit beam will affect the energy of the base station side to receive Msg.1 and receive subsequent signaling and data signals. Therefore, how to select the transmission beam of the terminal in the random access procedure is a problem that needs to be solved.

具体实施方式Detailed ways
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.
如图1所示，本发明实施例提供一种随机接入方法，包括：As shown in FIG. 1 , an embodiment of the present invention provides a random access method, including:
步骤11，在多个发送波束上分别发送与每个发送波束对应的随机接入前导码；其中，不同的发送波束对应不同的随机接入前导码。Step 11: Send a random access preamble corresponding to each transmit beam on a plurality of transmit beams respectively; wherein, different transmit beams correspond to different random access preambles.
本步骤具体包括：在多个发送波束上分别发送多个随机接入的第一消息Msg.1；其中，所述第一消息Msg.1使用的随机接入前导码是与承载所述第一消息Msg.1的发送波束对应的随机接入前导码。例如，在发送波束1上发送随机接入前导码1相当于在发送波束1上发送Msg.1，该发送波束1上承载的Msg.1使用的前导码为随机接入前导码1。This step specifically includes: sending multiple random access first messages Msg.1 on multiple sending beams respectively; wherein, the random access preamble used by the first message Msg.1 is the same as that used to carry the first message Msg.1. The random access preamble corresponding to the transmission beam of the message Msg.1. For example, sending random access preamble 1 on transmit beam 1 is equivalent to sending Msg.1 on transmit beam 1, and the preamble used by Msg.1 carried on transmit beam 1 is random access preamble 1.
需要说明的是，在多个发送波束上发送Msg.1时，不同发送波束上的Msg.1使用的随机接入前导码都是不同的。It should be noted that when Msg.1 is transmitted on multiple transmit beams, the random access preambles used by Msg.1 on different transmit beams are different.
步骤12，接收基站发送的用于辅助终端进行发送波束选择的辅助信息。该辅助信息是基于不同随机接入前导码或者不同发送波束，例如基站接收到随机接入前导码的功率值；再例如不同发送波束的优先级等，在此不作具体限定。Step 12: Receive auxiliary information sent by the base station for assisting the terminal to select a transmission beam. The auxiliary information is based on different random access preambles or different transmit beams, for example, the power value of the random access preamble received by the base station; another example is the priority of different transmit beams, which is not specifically limited here.
步骤13，根据所述辅助信息选择一个或多个发送波束进行随机接入过程的后续步骤。Step 13: Select one or more transmit beams to perform subsequent steps of the random access process according to the auxiliary information.
具体的，终端利用选择的一个或多个发送波束进行后续的随机接入过程和用户面上行传输。基于上述辅助信息，终端能够选择信号质量较好的发送波束来进行后续的信令和数据的传输，从而提升随机接入的成功率，并保证信令和数据传输的能量。具体的，信号质量较好的发送波束具体指：承载功率值较大的随机接入前导码的发送波束，或者优先级较高的发送波束等，在此不一一枚举。Specifically, the terminal uses the selected one or more transmit beams to perform subsequent random access procedures and uplink transmission on the user plane. Based on the above auxiliary information, the terminal can select a transmit beam with better signal quality for subsequent signaling and data transmission, thereby improving the success rate of random access and ensuring the energy of signaling and data transmission. Specifically, the transmission beam with better signal quality specifically refers to: a transmission beam carrying a random access preamble with a larger power value, or a transmission beam with a higher priority, etc., which are not enumerated here.
进一步的，本发明的上述实施例中步骤11之前，所述方法包括：Further, before step 11 in the above embodiment of the present invention, the method includes:
接收基站发送的每组随机接入前导码与终端的发送波束的对应关系；Receive the correspondence between each group of random access preambles sent by the base station and the transmission beams of the terminal;
根据所述对应关系，确定与不同的发送波束分别对应的随机接入前导码。According to the corresponding relationship, random access preambles corresponding to different transmission beams are determined.
本发明实施例中，基站将可用的在免于竞争的随机接入过程中可以在Msg.1中使用前导码资源分为N组，其中N为终端的发送波束的数量，N大于或者等于1。基站设置每组随机接入前导码与终端的发送波束的对应关系，并将所述对应关系发送给终端；具体的，基站可通过系统消息广播的形式告知终端其对应关系，则终端能够基于其对应关系，确定与不同的发送波束分别对应的随机接入前导码。In this embodiment of the present invention, the base station divides the available preamble resources that can be used in Msg.1 in the random access process without contention into N groups, where N is the number of transmit beams of the terminal, and N is greater than or equal to 1 . The base station sets the corresponding relationship between each group of random access preambles and the transmission beam of the terminal, and sends the corresponding relationship to the terminal; According to the corresponding relationship, the random access preambles corresponding to different transmission beams are determined.
进一步的，本发明的上述实施例中步骤11包括：Further, step 11 in the above-mentioned embodiment of the present invention includes:
步骤111，同时在多个发送波束上发送与每个发送波束对应的随机接入前导码。具体的，如果终端的发送天线阵列是数字波束赋形或者混合波束赋形，终端同时在多个发送波束上发送随机接入前导码。Step 111: Send a random access preamble corresponding to each transmit beam on multiple transmit beams at the same time. Specifically, if the transmit antenna array of the terminal is digital beamforming or hybrid beamforming, the terminal transmits random access preambles on multiple transmit beams at the same time.
或者，步骤112，在不同时间的多个发送波束上发送与每个发送波束对应的随机接入前导码。具体的，如果终端的发送天线阵列是模拟波束赋形，终端在不同时间上利用发送波束发送随机接入前导码。Or, in step 112, a random access preamble corresponding to each transmission beam is sent on multiple transmission beams at different times. Specifically, if the transmit antenna array of the terminal is analog beamforming, the terminal transmits the random access preamble using the transmit beam at different times.
较佳的，本发明的上述实施例中步骤12包括：Preferably, step 12 in the above-mentioned embodiment of the present invention includes:
接收基站发送的随机接入响应消息；所述随机接入响应消息中携带所述辅助信息。其中，随机接入响应消息也可称为随机接入的第二消息Msg.2。需要说明的是，基站可向终端发送一次或多次随机接入响应消息；例如，终端同时在多个发送波束上发送随机接入前导码时，基站可以通过一个随机接入响应消息指示多个随机接入前导码的功率；再例如，终端在不同时间上利用多个发送波束发送随机接入前导码时，基站可通过多个随机接入响应消息进行指示，每个随机接入响应消息仅指示当前接收到的随机接入前导码的功率；在此不作具体限定。A random access response message sent by the base station is received; the random access response message carries the auxiliary information. The random access response message may also be referred to as the second random access message Msg.2. It should be noted that the base station may send one or more random access response messages to the terminal; for example, when the terminal sends random access preambles on multiple transmit beams at the same time, the base station may indicate multiple random access response messages through one random access response message. The power of the random access preamble; for another example, when the terminal uses multiple transmit beams to send the random access preamble at different times, the base station can indicate through multiple random access response messages, each random access response message only Indicates the power of the currently received random access preamble; it is not specifically limited here.

例如，基站接收到的随机接入前导码1的功率值为A，基站接收到的随机接入前导码2的功率值为B，基站接收到的随机接入前导码3的功率值为C；则辅助信息可以包括：功率值A、功率值B以及功率值C；或者该辅助信息包括：随机接入前导码1的功率值大于随机接入前导码2的功率值，随机接入前导码2的功率值大于随机接入前导码3的功率值；或者该辅助信息包括：功率值排序由大到小依次为：随机接入前导码1的功率值、随机接入前导码2的功率值、机接入前导码3的功率值。For example, the power value of the random access preamble 1 received by the base station is A, the power value of the random access preamble 2 received by the base station is B, and the power value of the random access preamble 3 received by the base station is C; Then the auxiliary information may include: power value A, power value B, and power value C; or the auxiliary information includes: the power value of random access preamble 1 is greater than the power value of random access preamble 2, and the random access preamble 2 The power value of the random access preamble 3 is greater than the power value of the random access preamble 3; or the auxiliary information includes: the order of the power values from large to small is: the power value of the random access preamble 1, the power value of the random access preamble 2, The power value of the machine access preamble 3.

需要说明的是，发送波束的优先级是基于与发送波束对应的随机接入前导码的功率值确定的；通常情况下，随机接入前导码的功率值越大，发送波束的优先级越高。It should be noted that the priority of the transmission beam is determined based on the power value of the random access preamble corresponding to the transmission beam; in general, the larger the power value of the random access preamble, the higher the priority of the transmission beam .
例如，利用4bit来指示发送波束的优先级，则优先级由高到低可分别赋予1～15。例如，发送波束1的优先级为0001，发送波束2的优先级为0100，则发送波束1的优先级高于发送波束2的优先级。For example, if 4 bits are used to indicate the priority of the transmission beam, the priority can be assigned from high to low from 1 to 15 respectively. For example, if the priority of transmit beam 1 is 0001 and the priority of transmit beam 2 is 0100, then the priority of transmit beam 1 is higher than the priority of transmit beam 2.
